IdentityMap (Castor JavaDoc)

java.lang.Object
- org.castor.core.util.IdentityMap

All Implemented Interfaces:

java.util.Map
```
public final class IdentityMap
extends java.lang.Object
implements java.util.Map
```
An IdentityMap that uses reference-equality instead of object-equality. According to its special function it violates some design contracts of the Map interface.

Since:

0.9.9

Modifier and Type	Method	Description
`void`	`clear()`
`boolean`	`containsKey(java.lang.Object key)`
`boolean`	`containsValue(java.lang.Object value)`	In contrast with the design contract of the `Map` interface this method has not been implemented and throws a `UnsupportedOperationException`.
`java.util.Set`	`entrySet()`	In contrast with the design contract of the `Map` interface this method has not been implemented and throws a `UnsupportedOperationException`.

`java.util.Set`	`keySet()`
`java.lang.Object`	`put(java.lang.Object key, java.lang.Object value)`
`void`	`putAll(java.util.Map map)`	This optional method has not been implemented for `IdentityMap` instead it throws a `UnsupportedOperationException` as defined in the `Map` interface.
`java.lang.Object`	`remove(java.lang.Object key)`
`int`	`size()`
`java.util.Collection`	`values()`	In contrast with the design contract of the `Map` interface this method has not been implemented and throws a `UnsupportedOperationException`.
